Question

Two angles are supplementary. One angle measures 16 degrees less than 3 times the other. Find the measure of each angle.

Answer 1

Two angles are supplementary one angle is 4 degrees less than three times the other find the measures of the angles

x + y = 180

x = 3y - 4

3y - 4 + y = 180

4y = 184

y = 46

x = 134

Answer 2

Y = 1st angle
X = 2nd angle

Y = 3X - 16

90 = X + Y

90 = X + (3X -16)

Do some algebra and X=26.5

So substitute x back in to find y, and Y=63.5
